Question

我有一個PHP代碼：

function display_categories_list($categories_list) { 

    $display .= '<ul data-role="listview" data-theme="d" >'; 
    for($i=0; $i<count($categories_list); $i++) { 
     $display .= '<li><a href="javascript:" class="displayStoresListByCategoryBtn" id="'.$categories_list[$i]['id'].'">'; 
     $display .= '<h3>'.$categories_list[$i]['name'].'</h3>'; 
     $display .= '<span class="ui-li-count"><font color="red"><small>'.$categories_list[$i]['nb'].'</small></font></span>'; 
     $display .= '</a></li>'; 
    } 
    $display .= '</ul>'; 

    return $display; 
} 

我無法訪問SQL查詢和我要訂購我的「名alphabeticals ASC」的結果。

我該怎麼辦？

Answer 1

$categories_list[0]['name'] = "Bob"; 
$categories_list[0]['id'] = 1; 
$categories_list[1]['name'] = "Carol"; 
$categories_list[1]['id'] = 2; 
$categories_list[2]['name'] = "Ted"; 
$categories_list[2]['id'] = 3; 
$categories_list[3]['name'] = "Alice"; 
$categories_list[3]['id'] = 4; 

// Obtain a list of columns 
foreach ($categories_list as $key => $row) { 
    $tmp[$key] = $row['name']; 
} 

array_multisort($tmp, SORT_ASC, $categories_list); 

print_r($categories_list); 

給出：

Array 
(
    [0] => Array 
     (
      [name] => Alice 
      [id] => 4 
     ) 

    [1] => Array 
     (
      [name] => Bob 
      [id] => 1 
     ) 

    [2] => Array 
     (
      [name] => Carol 
      [id] => 2 
     ) 

    [3] => Array 
     (
      [name] => Ted 
      [id] => 3 
     ) 

)
